Well I sorta see your point. However judging from a PC98 screen shot v. my Apple display. I would say there is not so much difference since those screens had a smaller display ( cut-off) before 320X240 was normal, or even 640X480. This is a great comparison article and I wish I had done one myself.

However in my opinion it as a player it only matters when I play the game and not taking screen shots. When I do I go for 320X240 or the original display units. If it is a GBA game then forget it. The amount of shading and photo-shop affects makes the game un-viewable to the normal eyes.
